You could argue about the loop itself, after all K&R specified "for(;;)", but the other commonly used (ergo idiomatic) infinite loops use precisely the same number of lines. "while(1)" is a perfectly idiomatic manner to create an infinite loop.
Likewise a void return type for main was entirely legal until C99. The BSD yes(1) I've laying around only prints the first argument, so flag parsing? What flag parsing?
Yes in nine lines of C inclusive of preprocessor macro invocations and white space.
#include <stdio.h>
int main(int argc, char **argv) {
const char *phrase = argc > 1 ? argv[1] : "y";
while (1) {
printf("%s\n", phrase);
}
return 0;
}If it's more comfortable you can also declare argv as an array of character arrays e.g. char *[], but that won't change the line count.
the Go code has MORE functionality (flag parsing) with LESS code. yes its not as fast, and yes the executable is larger, but for many, thats a good tradeoff for the extra standard library features, and the reduced LOC/code complexity. sadly as of yet, I haven't seen any cogent technical arguments against my points thus far.
I'm genuinely curious to hear your argument.
previous comments have demonstrated this not to be the case, so I will stand by my previous points. I have already made over 10 comments on this one topic, so if any aren't already convinced, they never will be, either because they disagree with the tradeoff, or they just have stockholm syndrome for C.

Your code does not have more functionality than GNU's yes as written. It's less code you have to write because of the flag parsing code that has already been written, and it's incompatible with GNU's yes because yours requires -m to change the message.
it has flag parsing
There is no requirement to parse flags for the basic functionality of yes. You implemented that yourself. You can remove your own requirement whenever you want. You don't need to parse a flag, at most you need to parse a string from the command line arguments.
I wonder at this point how you define "flag".
That's the whole point. Every single command line program needs command line parsing. Go helps me get the job done, C forces me to write my own parser, or find some third party one.
